He was the fourth of eight children of Ivan Ivanivich Churyumov and Antonina Mikhailovna Churyumova. His father was declared dead during World War II in 1942. In 1949 Churyumov's family moved from Nikolayev to Kiev. After seventh grade, he entered the Kiev Railway College, graduating with honors in 1955. He received a recommendation for admission to higher education. He entered the Physics Department of Kiev State University. During his third year of study, he was disappointed to be assigned to the faculty of optics, instead of theoretical physics. However, he continued to attend lectures on theoretical physics, even though the authorities disapproved, and he was eventually moved to the faculty of astronomy, where there were vacant places. After his graduation in 1960, he was sent to the polar geophysical station at Tiksi Bay in the Yakut ASSR. There he studied the aurora, earth currents and ionosphere. In 1962, he returned to Kiev and went to work at the plant "Arsenal", where he participated in the development of optical components for the Soviet military and space programs. After finishing postgraduate studies at Kiev State University, he continued working as Fellow at the Department of Astronomy at university. As part of his work he observed the comets at the astronomical observatory of Kiev University in the villageLisniki as well during astronomical expeditions in the highlands of Central Asia, the Caucasus, Siberia, the Primorsky Krai, in Chukotka and Kamchatka. In 1969 the University equipped an expedition of three people, including Churyumov and Svetlana Gerasimenko, for surveillance of periodic comets in Alma-Ata astrophysical observatory. In 1972 he defended his first post-graduate scientific degree with thesis "Studies of comets Ikeya-Seki, Honda, Tago-Sato-Kosaka and new periodic comet Churyumov-Gerasimenko from photographic observations." In 1993 he defended his doctoral thesis on "Evolutionary physical processes in comets" at the Institute of Space Research, RAS. Beginning in 1998 Churyumov was a professor at Taras Shevchenko National University of Kyiv. In January 2004 he was appointed as director of the educational center Kiev Planetarium. Churyumov died in the night of 13-14 October 2016 in hospital in Kharkiv.
